mer'al 10, is provided with any suitable screen material 11 secured tosaid'franie 10' as by the moulding strips 12. Theup'per and outer edge13 of the top member 14 of the frame 10 is beveled as indicated tocorres-pon'd with and abut the inclinedsur face 15 of'tlie" casing 2. Ina similar way the bottom strip 16' of the frame" 10 is pro vid'edwiththe I in'c'lined surface 17- to correspend with and" substantially itagainst the inclined;- surface 18' of the window sill 6 when said frame10 is in closed position The entire relative tothe window casing. framelO'is adapted to swing on the hooks 20"s"e'cu'redto the upper casing 2,s'aid'hooks' being engaged by the slotted members 21 secured to theupper member 1 1 of theframe 10, in the usual= and well known Secured toone of the side mem bersysuch as 25,-of thefr'ame 10 is the angle member26 provided with the pin 27' pivotallv-supportingaispacingjbar 30.

hespacing'bar 30; seeFigures 1 7 8' and 11, has cam notch 31 in one edgethereof near the pivot 27, a plurality of holes" 32 disposed in spaced Irelation to each other, and u-liolding notch 33' located in the sameedge withthe cam=notch 31 but disposed be- ,yond theholes-32 and nearthe free'end of the bar 30.'- The extreme free end of the bar' 30 isbentsubstantially at right angles to the mainbody portion' thereof' to-forma foot 35 t-he' side edges of which are inclined relatively to said bodyportion as clearly shown in Figures 45, 5,=6'and 10. This foot 35-isprovided with a suitable opening 36 to receive the-bolt of the latchtO'secured to said frame lOnearthe bottor'n member 1 5 there of. Alsoone edge of the foot 35 isbeveled as at 3 7 to aid'the' bolt of'said-latch 10 in engaging the aperture'36'of-the spacing bar,

allaswill beclear from the drawings.

The latch 4e0maybe of any suitable type such as that indicated in thedrawings where in the boltel" thereof is controlled asby the spring 42and operated'by the thumbkneb 43 secured to the said bolt and workingthr'o'ug'ha slot 14 in'the casing'o'f the liI-teh- 10. Said latch is sodisposedjon the frame 10- of the screen that the spacing bar' 30 whenswung from its pin27 downwardly willcause be engaged by'the' bolt 41 ofsaid latchas- Ill (ill

window is the bracket 50, see Figures 1, 6, 7, 8 and 9. This bracket 50comprises the brltge portion 51 provided with a thumb screw threadedtherethrough and having a shank suliiciently long to engage one of theholes of the spacing bar 30 to hold the latter against movement. Thebracket 50 is secured to the frame member at one end by a screw disposedthrough the apertured car 5-lof the said bracket, said ear 5 contactingwith the frame member 5 and spaced from the bridge 51 as by theconnecting portion 55 of said bracket. The other end of the bracket 50is formed a little differently, see especially Figure 9, being providedwith an apertured car 56 secured to the bridge 51 by the connectingportion 57 which is of less length than the other connecting portion 55.so that said car 56 is parallel to but spaced from the frame member 5 inorder that the securing bar 30 may be passed between said car 56 and theframe member 5 when desired. A screw (30 passed through the aperturedcar 56 into the f 'ame member 5 will secure said spacing bar 30 withinthe bracket member 50 as will be readily seen from the drawings.

The operationbf the device is as follows: W hen the opening, such as thewindow in the drawings, is desired to be closed by the screen 11, theframe holding this screen is swung on the hooks secured to the casing 2.The screw 60 of the bracket member 50 secured to the frame 1 is thenremoved and the spacing bar inse "ted within the bracket 50 by passingthe bar between the car 56 of the bracket and the side member 5 of theframe, whereupon the screw ('30 is then replaced to prevent the spacingbar 30fron1 leaving the said bracket. The frame 10 is then allowed toswing in toward the window frame 1 and the bar 30 turned about the pivot27 in a downward direction and the foot moved toward the bottom member16 of the frame 10 so as to have the aperture 36 of the said footengaged in locked position by the bolt 41. of the latch ll). During thisoperation the inclined edge 13 at the top of the frame 10 will abut theinclined edge 15 of the casing and likewise the inclined edge 17 at thebottom of the frame 10 will substantially litthe inclined surface 18 ofthe sill 6. The hooks 20 and the socket members 21 engaged thereby areso disposed that the frame 10 will tightly lit the casing 2 as well asthe frame 1. Also the spacing bar 30, the angle member 96, the bracketmember 50, and the latch l0 are all so disposed relative to each otherthat when the screen is in closed position as shown in Figure 2, thebottom of the frame 10 will be in close contact with the bottom framemember elof the window frame, and the intermediate portion of the screenframe 10 to which the angle member 26 is secured will be forced intoclose contact with that portion of the side members 5 of the windowframe to which the bracket is secured.

This drawing of the screen frame 10 into close contact with the windowframe by means of the spacing bar 30 is accomplished as follows Vvithspecial reference to Figures 7 and 8 it will be observed that the camnotch Ell comprises the short inclined surface disposed nearly at rightangles to the longitudinal axis of the spacing bar 30, and the longerinclined surface 71 disposed at but a slightangle to the longitudinalaxis of said bar. Further it will be observed that the screw (50 is sodisposed in the side member 5 of the window frame that the surfaces ofthe cam notch 31 will normally at all times contact with said screw.

lVith special reference to Figure 7 it will be noted that the frame 10is advancing toward the window frame, as indicated by the arrows, tooccupy its closed position. During this movement the spacing bar 30 willride on the surface of the screw (50 until the cam notch 31 is reachedwhereupon the bar 30 by its own weight will cause the inclined surface71 of said notch to be engaged by the screw 60. Continued movement ofthe parts shown in solid lines in said Figure 7 will *ause the screw 60to occupy the deepest portion of the notch 31 thus bringing the partsinto the position shown in dashed lines. Figure 8 shows the screen frame10 in full closed position and from this figure and Figure 7 it will beseen that during the final step of closing the screen frame 1.0 theshort inclined surface '70 contacts with the screw (it). During thesuccessive steps there fore in closing the screen 10, it will be seenthat the screw (30 serves as a fulcrum for the spacing bar 30 as alever. That is to say, the free end of the bar 30 becomes the operativeend of a lever which when turned about the screw 60 as a fulcrum forcesthe screen frame 10 into close contact with the window frame 1 due tothe spacing of the cam notch 31 and the said screw 60. \Vhcn the fran'ie10 has contacted with the side members 5 of the window frame as abovedescribed, the spacing bar 30 is in a depending position such as shownin Figure 2 and may be then locked in such position as by the bolt 41 ofthe latch 40. Thus it will be seen that the screw (30 serving as afulcrum detcrmil'ies the position of the pivot pin 27, as well as theposition of the foot 35 of the spacing bar 30 when the screen is closed.

In the modified applicatiom shown in Figure 11, the spacing bar 30,till! angle member 26, and the latch 4-0 have been applied to the coverof a trap, or man-hole. such as are provided in roots. The bracketmember 50 is applied to the box farming of the manhole as shown andbears the same relative position to the spacing bar 30 and latch 40 asit did in its application to the window and screen .above described.That is to say, the cover 100 is hinged as at 101 to the box framing.102 in the .roof 103, and the angle member 26 is disposed on the underside of said cover in'such a position, relative to the latch 'also onthe under side of said cover. that when the cover is in closed positionas shownin solid lines in Figure 11 the foot 35 of said bar 30 may beengaged in locked position by the bolt 4 1.of the latch, exactly as wasthe case in Figure 2 of the drawings. If desired to open the cover 100only partially or to a position as indicated in dashed lines in saidFigure 11, the thumb knob 52 on the bracket is engaged in such a hole 32as will give the desired opening of said cover. In every respect thelatch 40, the spacing bar 30 and its associated member 26, and thebracket 50 are the same as the latch, spacing bar, angle member andbracket as disclosed above in relation to a window screen, and thereforethe operation of these parts is exactly the same as was the operationabove described.

In Figure 12 is illustrated a modified form of bracket corresponding tothe bracket 50 above described. there is provided a casting comprising abase plate 120 adapted to be permanently secured to the frame 121 of anyopening as by the screws 122. Rigidly secured at one end of the plate120 is the lug 123 and likewise at the opposite end is a similar lug124. Suitably secured in pivotal relation to the lug 123 as by the looserivet 125 is the bridge or plate 126 of such a length as will extendfrom the lug 123 to the lug 124 and which may be secured to the lug 124as by the screw 127 threaded into said lug. Thus the bridge 126 issecured to the base plate 120 in spaced relation thereto sufficient toslidably= receive the spacing bar 30. Disposed centrally of the bridge126 is the thumb screw 130 threaded through said bridge and adapted toengage any one of the holes 32 located in the spacing bar 30. Theadvantage of the modified form of bracket shown in Figure 12 over thebracket 50 above described is apparent but may be briefly stated asfollows. The continued removal and insertion of the screw from thebracket 50 in order to allow the spacing bar 30 to be positioned andremoved from the said bracket will in time so destroy the material ofthe window frame as to make it imperative to either locate the screw 60in a differ ent portion of the window frame or else move the entirebracket 50 to a difierent position thereon. The former contingency wouldbe a serious mistake since the screw 60 serves as the fulcrum for thespacing bar 30 in order to secure the closure in tight relation to theopening.

The construction shown in Figure 12 ohviates this difficulty, in thatthe bracket 120 In this modificationis adapted to bepermanentlysecuredto the frame ofthe opening and only thescrew 127 removed in order topermit the'placement and displacement .of the spacing bar 30. Since the.parts 120, 123, 124, 125, 126 and 127 are all constructed of metal.there will be little if any wear on the parts as will be obvious. Inthis respect of course the lug 124 serves as the fulcrum for the spacingbar 30 and as its position is always fixed relative to the windowcasing, the continued removal of the spacing bar 30 will never cause toexist an ultimate state of condition as that described above with theuse of the bracket 50 and screw 60. WVith either type of bracket, thatis, 50 or 120, it is to be noted that the closure may be retained in anopen position by means of the notch 33 in the bar 30, see Figure 10,which will engage with the proper element of the bracket, as clear fromFigure 1 of the drawings. That is to say, the notch 33 being at the freeextremity of the spacing bar 30 will, when engaged with the screw 60 ofthe bracket 50, or the lug 124 of the bracket 120, hold the closure in asubstantial open position.

It is to be understood that the closure fasteners above disclosed willbe utilized in pairs. That is to say, in the use of these fastenersthere will be one applied to the left side of said closure and anotherfastener disposed on the right side of said closure. Stated in stillother words, as is well understood, these fasteners will be made inrights and lefts.

It is obvious that those skilled in the art can vary the details ofconstruction as well as the arrangements of parts without departing fromthe spirit of the invention, therefore it is not desired to be limitedto the foregoing except as may be called for by the claims.
